Detailed Description
As shown in FIG. 1, the popularization data processing method comprises a sending end, a server and a client;
the transmitting end acquires popularization data and popularization conditions;
the server sends promotion data to a client matched with the promotion conditions;
the client responds to the promotion data, and the client sends a transaction request to a sending end of the promotion data through a server;
the method for sending the transaction request to the popularization data sending end by the client through the server comprises the following steps:
the client converts the transaction request into first encrypted data by a first encryption algorithm, and the client sends the first encrypted data to the sending end through the server;
the sending end encrypts the first encrypted data into second encrypted data through a second encryption algorithm, and the sending end sends the second encrypted data to the client through the server;
the client converts the second encrypted data into third encrypted data by using a first decryption algorithm corresponding to the first encryption algorithm, and the client sends the third encrypted data to the sending end through the server;
the sending end converts the third encrypted data into a transaction request by utilizing a second decryption algorithm corresponding to the second encryption algorithm.
According to the method, the client side sending the first encrypted data to the transaction request can decrypt the second encrypted data encrypted by the sending end, the third encrypted data decrypted by the client side is sent back to the sending end, and the sending end decrypts the second encrypted data, so that even if the server transmits data between the sending end and the client side, the data is always encrypted by one or two encryption algorithms, and the sending end and the client side can successfully decrypt the encrypted data, so that accuracy of data transmission is guaranteed, and the data is prevented from being maliciously acquired and leaked by the server.
Referring to fig. 1, the client encrypts and decrypts the transaction request with a first encryption algorithm and a first decryption algorithm to avoid the server from obtaining the transaction request, and the sender encrypts and decrypts with a second encryption algorithm and a second decryption algorithm to avoid the server from obtaining the transaction request, so that the privacy of the user is protected, other hackers are prevented from invading the server, the sender and the client are counterfeited to complete the transaction, and the benefit of the real sender is protected. The server as the carrier is required to complete the data transportation, and the carrier is encrypted at least once, so that the confidentiality and isolation of the data can be facilitated.

the user terminal converts the transaction request into first encrypted data according to a first superposition encryption method configured by the first classified data;
the sending end encrypting the first encrypted data into second encrypted data by a second encryption algorithm comprises the following steps:
the client identifies second classified data corresponding to the first superposition encryption method, judges whether the second classified data is matched with prestored first classified data corresponding to the popularization data, encrypts the first encrypted data into second encrypted data by the second superposition encryption method if yes, and sends an alarm signal to the server if no.
The invention avoids man-in-the-middle attack by repairing the first encryption method and the second encryption method. Specifically, in order to avoid a hacker or a server disguising a transmitting end receiving a transaction request, the first encrypted data is directly received, the second encrypted data is decrypted into third encrypted data by a spoofing client, and the server or the hacker decrypts the third encrypted data by itself by using a method of the server or the hacker. Thus, the benefits of revealing the privacy of the user, knowing the transaction request of the client by the competitor and the sending end are infringed. In order to avoid this, the client and the sender establish a consensus mechanism, that is, the sender and the client can classify the promotion data into the same first classification data, so that better identity information confirmation can be realized, and man-in-the-middle attack can be avoided.
For example, the man-in-the-middle attack described above is: the hacker or the server impersonates the sender and performs the same operation, and intercepts the transaction request, thereby disabling the whole system.
In order to avoid the man-in-the-middle attack, first classification data of all promotion data, such as promotion data of advertisements of law-gigging litigation agents, are pre-stored in a database of a transmitting end and a database of a client end, and are uniformly classified into first classification data of law-gigging class. The first classification data may be understood as a consensus class label. The sending end of the first encrypted data of the receiving client can identify the encryption type through the first classified data according to the encryption type of the first encrypted data, if the encryption type is matched with the first classified data, the first encrypted data is encrypted into second encrypted data, the second encrypted data is sent to the client, and if the second encrypted data is not the second encrypted data, the server can be directly alerted.
The above consensus mechanism may also be an algorithm that generates 0 in the first 5 bits of the hash value of the special code, which may be generated by the sha256 algorithm, when transmitting, so as to obtain a consensus.
Referring to fig. 1, the encrypting the first encrypted data into the second encrypted data by the second encryption method includes:
the encryption and decryption process of the first superposition encryption method and the encryption and decryption process of the second superposition encryption method are not mutually influenced.

and when the first classified data corresponds to a second algorithm, configuring the second algorithm as a first coincidence encryption algorithm, and configuring the first algorithm as a second coincidence encryption algorithm.
The invention can pre-store the algorithms which are not affected each other as few as possible through the two algorithms respectively, and effectively distinguish whether the sending end and the client end use the correct coincident encryption algorithm, thereby not only occupying less memory, but also effectively avoiding man-in-the-middle attack.
Referring to fig. 1, the first algorithm is: shifting each letter forward or backward by n bits in 26 alphabets, wherein n is the remainder of dividing the hash value of the first classified data obtained by the SHA256 algorithm by 26;
the second algorithm is as follows:
the transmitting end and the client pre-store the line number corresponding to the first classified data;
and adjusting the line number of the transaction request or the first encrypted data according to the line number.

The encryption types may be: shifting each letter forward or backward by n bits in the 26 alphabet, e.g., abc forward by 1 bit is bcd. The above n may be determined by a hash value of the first classification data. For example, the hash value is calculated by the sha256 algorithm, and the remainder of dividing the hash value by 26 is 2, and n is 2. It is to be noted that z may become b when moving 2 bits to the right.

For example, the first classification data is a law class. The corresponding line number is 654321, and the line number of the transaction request or the first encrypted data may be 12345; that is, the first encrypted data is divided into 5 rows, the first row corresponds to the first row and the second row corresponds to the second row, and the sixth row is blank, and the first row is adjusted to be blank, and the second row is adjusted to be the fifth row. Blank 54321. Thereby, the first classified data corresponds to the first classified data, and the first classified data is encrypted.
The number of the line number corresponding to the first classified data is pre-stored in a database.
Wherein the number of bits of the number is equal to or greater than the number of lines of the first encrypted data. And when the number of the digits is larger than the number of the lines of the first encrypted data, supplementing the contents of other lines of the first encrypted data as blank.
Wherein encryption of one encryption method does not affect encryption and decryption of another encryption method.
